A curved lense of that shape magnifies anything.
Simply put, it means you'll want your reading material about 1.33 meters away from your eyes. The letters will look about as large as they always do at a distance of 1.33 meters, but with the glasses on you'll be able to focus on your reading material comfortably.If you'd rather have your book or screen 1 meter away, use +1 diopter lenses; half a meter away, use +2 diopter lenses; 0.33 meters away, use +3 diopter lenses and so on. The closer you put the reading material, the larger it appears (just like always). Of course your mileage may vary, so use these numbers as a starting point to see what works for you.The general idea is that those of us with so-called "normal" vision (or vision that's been corrected to normal with glasses or contact lenses) are focused on objects a long way away when our eyes are relaxed. By using reading glasses and putting our reading material one focal length in front of the glasses, we make the reading material appear to be a long way away, without changing it's apparent size. The focal length of the lenses in meters is 1 divided by the power in diopters. One might say the purpose of reading glasses isn't to magnify, it's to be able to focus comfortably.Sometimes optics like magnifying glasses and telescope eyepieces are spec'ed in terms of magnifying power. Magnifying power can be calculated as the power of the lens in diopters, divided by 4. The idea here is that someone decided 250 mm is a reasonable value for the closest "normal" people can focus, so they use 4 diopters for the baseline to compare against when considering the apparent size of objects viewed through a magnifying lens.

Automatic meter reading technology allows utility companies the prospect of reading meters off site as the technology can read meters remotely. This allows the company to cut labour costs.
Objects that are 50 meters long could include a standard Olympic-sized swimming pool, a tennis court, or a basketball court. In terms of natural objects, a blue whale, the largest animal on Earth, can reach lengths of up to 30 meters, which is close to 50 meters. Additionally, certain types of large trees, like sequoias or redwoods, can grow to be around 50 meters tall.
Gravity causes objects to accelerate at a rate of 9.8 meters per second squared.
Electric meters are read remotely using advanced technology such as smart meters and automated meter reading systems. These devices use wireless communication to send meter readings to utility companies without the need for manual readings by a person.
There is not really any requirement in length for you to measure in meters. You have to use your own judgement to choose the right unit of measurement.
Space means distance in meters between objects or locations.
That is 10 meters - approximate the length of a house, or the height of a tree.
